lNIPRO'VENIENT IN CASTlNG ElVxlBOSSED TYPE.

Specilication forming part of Iletteis Patent NoA 30,293, dnb dOttchertl,1560.

To @ZZ 'zt-hom, it may concern.'

Be itknown that I, Tsi-ilo C. Bursar, o1' the cityof Philadelphia andState of Pennsyl` Vania, have invented a new aud Improved Mode o1`Making and Casting lEmbossed or Pointed Type, and I do hereby declarethat the following a t'ull and exact description thereof, referencebeing had tothe accompanying drawings, and to the letters ol" referencemarked thereon.

The nature 'of my invention consists in providing a mold, and what Iterm a double matrix, and to enable othersskilled in the art to make anduse my invention I will proceed to describe its construction andoperation.

Figure Ais a side tjiew ot mold and n1atrix or die made ot' cast-iron intwo parts. Fig. B is a plan or edge view. Fig. C is an end view. Fig.Dis a side view of matrix with points ready for casting when placed inmold. Fig. E is the face-letter. Fig. l." is the top orguideletter. Fig.G- is the bolt for holding in the guide-letter and points. Fig. ll. isthe set-screw for holding up bottoni letter. Fig. I is the gate forpouring in the metal Fig. lTis the butt-on for holding .in the bolt thatholds in the points and top letter. Fig. K is the points in frame readyfor casting. Fig. Il is the frame matrix or'liolder, which formsthe-back of mold, and holds the letters and points ready for casting.Fig M is the -slide forming the frontbt' gate to mold. Fig. N is the pinfor holding in matrix or trame.` Fig. O O a-re the openings inguide-letter N l'or putting in the points.

rlhe mold is made of cast-iron in two parts Similar to the mold now inuse i'or casting ordinary type, except it is open-on the face to receivethe 'frame holding the top and botten letters and a slide forming thefront of tht gate to pour the metal in, and a pin attached to slide tohold in the frame or matrix whilt casting, The niatrix forbottomletteris made by casting on a patteru-letteror by drilling orpunching into a brass, copper, i'ron, or steel plate the depth desiredto have the points to project below the surface of the end of type whencast. The top letter is made by a pattern-letter used as a punch andpunched into a piece ot' brass, iron, copper, or steel, and tiled thesize the letter is intended to be, and to correspond with 'the bottoniletter in shape. The matrix has two letters, one on each end. '.lheletter on the lower end is perfora-ted with points or earities, formingthe letter intended to be east. The letter on the upper end is made tocorrespond in form with the letter on lthe lowerend. The letter on theupper end is made the same as a pattern-letter i'or casting the commontypes, except it has one or more openings on the top for the purpose ot'placing in the steel, brass, or` other pointed wires, which, when placedin, will form the entire letter or letters in points or projections. lhetwo let-ters above are placed in a horizontal piece ol" brass, iron, orsteel, the distance apart the length the type is intended to be, thesaid piece forming the back et' the mold. rllhe bottomlettcr is soarranged by a screw springer wedge that when the east is made that byloosening the screw spring or wedge the bottom letter will leave thepoints and the casting or type drop out of the mold. After the lettersabovedescribed are placed in the horizontal piece of metal that Jformsthe back ot' the mold, the points, after being previously tinned,sharpened, and made theflength to lit the two letters abbve describedand placed therein, the'niold is filled with ty pe-metalv or any othermetal answering the purpose. rI"he type cast in the above way will fornia solid type in the body with projecting points forming any letter orcombination of letters desired.

Having described my improvement, I claim and desire to secure by LettersPatentl. The combination of the bottoni and top letter or letters in aframe made of iron, brass, copper, or an y other metal suitable for thepur pose.

2. The arrangement of the openings in the top letters for putting in thesteel, iron, or brass wire forming the points or projections on the faceof the type.

3. .The combination of one or morev guideletters :1t-the top with one ormore letters at the bottom formed so as to give the desired shape inpoints or projections to the letters or designs to be east.'

4. 'The combination of separate pieces of 6. The mold, in connectionwith the matrix steel7 iron, or brass wire, round, square, or slide andpin, as described. :my other shape suitable, in connection with immo andguide and bottom letters or designs. ISAAC C. BRYANT.

rThe combination of points so as to form n letter or lettcrs andsoldifying;` them by Witnesses: casting type or other metal around themin a W. G. CoNNons, mold and double matrix, as described. L. R.FLETCHER.
